About the Site

 I try to log my observing and related activities in a regular blog - sometimes there will be a delay but I usually catch up. An index of all my blogs is on the main menu at the top of the page with daily, weekly or monthly views. My Twitter feed is below. I am also interested in photograping wildlife when I can and there is a menu option above to look at some of my images. I try to keep the news feeds from relevant astronomical sources up to date and you will need to scroll down to find these.

The Celestron 14 is mounted on a Paramount ME that I have been using for about 10 years now - you can see that it is mounted on a tripod so is a portable set up. I still manage to transport it on my own and set it all up even though I have just turned 70! It will run for hours centering galaxies in the 12 minute field even when tripod mounted.

« Day 133 Saturday 2nd August 2014 201 galaxies imaged - Closed loop slew to centre objects worked well. | Main | Day 131 Thursday 31st July 2014 Moon arrives to hide the light of thousands of galaxies. »

Day 132 Friday 1st August 2014 New reduction set and 243 galaxies imaged. Siding Spring images.

A clear night - I took 20 Flat, 20 Dark and 20 Bias Frames - I used my Flat Frame Technical Interface for the Flat frames (a white T-Shirt!)

I took 30 second images of 243 galaxies in one hour blocks of increasing RA with decreasing Declination in each block and applied the reduction frames to each of these. Image numbers were 1572 to 1751.


Earlier in the week I took some images using the telescopes at Siding Spring in Australia. Here they are:

IC 5152

The above image is a jpeg image, I opened the original FITS file in SkyX for the Siding Spring location.

The SkyX has an option to use the data in the FITS data file to adjust the SkyX chart to the date and time of the photograph.

The advantage of this is that if there were any solar system objects around when the photo was taken - such as Minor Planets or Comets -  then they will show up on the chart in the position they were in when the image was taken.


I set the chart to the time of the photo and then used image link to solve the plate.


and linked the image to the chart
